lower portions of tlie lobes and face oclireous ; mouth black 

 and with a black spot on each side ; body yellow, shading 

 into greenish-yellow on the sides ; two ill-defined deeper dull 

 greenish sub-dorsal stripes ; usual spots dull white, large and 

 prominent ; spiracles very pale brown ; a black lateral dot 

 above those on the second segment. (0. Fenn.) 



May, June, July, on oak, drawing together a leaf or a lobe 

 of a leaf, partially, with silk, and sheltering through the day 

 on the underside, but coming out at night to feed. The 

 habitation is not so closely drawn together as in previous 

 species, and the larva is readily shaken out of it by beating, 

 but it is also quite easily discovered by looking upward at the 

 outside leaves of the high oak bushes, when the larva may be 

 seen half-curled under the concave leaf. 



Pupa stout, wrinkled, tapering considerably ; anal extremity 

 furnished with a long double-hooked spike ; incisions deeply 

 cleft. Dull red, not highly polished; in a compact silken 

 cocoon among moss or rubbish adhering to the trunk of a 

 tree or under the surface of the ground. (0. Fenn.) In this 

 state through the winter and not unfrequently during more 

 than one year. 



The moth may occasionally be found sitting on the trunk 

 of an oak tree in the daytime, but its colour and markings 

 mimic so closely the lichen and moss on the trunks that it 

 may probably be often overlooked. It appears to be rarely if 

 ever taken at sugar, or at exuding sap, and its habits are very 

 obscure, though it is known to fly at night. The vast majority 

 of specimens in collections are reared from the larva or pupa. 



Apparently confined to woods and wooded districts, and 

 found, though not commonly, in Surrey, Sussex, Hants, 

 Berks, Dorset, Devon, Cornwall, Somerset, Gloucestershire, 

 Herefordshire and Worcestershire. Probably more frequent 

 in South Wales, since I have found the larva rather commonly 

 in a large wood in Pembrokeshire. Very scarce in the 

 Eastern Counties and almost absent from the Midlands,
